Tips: Like its predecessors, Vileplume's stats are only average, but the Grass/Poison type is not about attack power anyway. Vileplume is all about status-changing attacks like Stun Spore, Sleep Powder, Toxic, etc. Gloom doesn't naturally evolve into Vileplume, which is a good thing, since Vileplume won't be able to learn many of Gloom's and Oddish's techniques. So be sure that you've got all the moves you want before you use the Leaf Stone. Once Gloom turns into Vileplume, you can only learn new techniques with the help of TMs and HMs. Vileplume's Poison and Grass techniques work well against Water, Ground, Rock, Grass, and Bug opponents. For example, Solar Beam and Mega Drain can help take out even the toughest Ground opponents, and the status-changing attacks like Sleep Powder, Stun Spore and Toxic can instantly turn a battle around to your favor. If you're looking for a Grass/Poison Pokemon better suited for battle, stick with Venusaur.

What do you do when going up against Vileplume? Fire, Ice, Flying, Bug and Psychic attacks will all work well -- but you should generally stay away from using a Bug Pokemon against Poison types.
